# OUTSCALE Load Balancer Unit (LBU): a managed load balancer in front of backend VMs
# ("About Load Balancers"). That page states what drives the defaults: listeners speak
# HTTP/HTTPS or TCP/SSL and a frontend protocol must match its backend level, an
# internet-facing LBU gets a public DNS name while an internal one is reachable only inside
# the Net's CIDR, health checks decide which backends receive traffic, TLS 1.1 to 1.3 is
# supported, and sticky sessions exist for HTTP/HTTPS listeners only.
